Title: Receiver
Inventor: NARITA TAKAMITSU
IPC: H04B10/00
Filed: 1980-06-28
Abstract: PURPOSE:To prevent a receiving circuit unit from malfunctioning by stacking a filter part which permits only light of >= about 700nm wavelength and a filter part equipped with a louver part which limits an angle of light incidence within a permissible range. CONSTITUTION:A filter structure B is constituted by stacking a filter 25 and a filter 27. This filter 25 permits light with >= about 700nm wavelength to pass through it. The filter 27, on the other hand, is equipped with a louver 272 in a light-transmittable body 271, and the louver 272 transmits light arriving as shown by an arrow a1 and intercepts light arriving as shown by arrows a2, a3, etc. Consequently, a TV receiver is used for a general purpose, light from a fluorescent lamp in the direction of the arrow a1 is intercepted by the louver to suppress the malfunction of a receiving circuit unit sufficiently.

Title: Double-separated fluid valve
Inventor: TAKANO MICHIO
IPC: F16K31/10
Filed: 1979-07-13
Abstract: PURPOSE: To prevent corrosion in the movable part of a diaphragm-type solenoid valve, by providing two diaphragms, in which one of the two diaphragms is integrally constructed with the valve and the other is screw-secured to said valve, and forming a vent hole linked to the outside between the both diaphragms.  
     CONSTITUTION: Two diaphragms are fixed in such a method that the first diaphragm 12 is integrally constructed with a diaphragm valve 11 and the second diaphragm 13 is secured to said valve 11 by screw-mounting the female screw of the diaphragm 13 to the male screw formed on a stem of the diaphragm valve 11. Between the first and second diaphragms 12, 13 a spacer ring 17 is inserted in which an externally linking vent hole 14 is provided. In this constitution, infiltrating fluid from the first diaphragm 12 is diluted by the vent hole 14 and diffused to the outside. While infiltrating corrosive fluid from the second diaphragm 13, being of fine quantity further being blocked by the screw tightening of the second diaphragm 13 to the stem of the valve 11, never leaks from a gap, thus capable of preventing corrosion at the movable part.

Title: Taper machining in wire electric discharging machine
Inventor: KINOSHITA MITSUO
IPC: B23H7/06
Filed: 1984-05-01
Abstract: PURPOSE:To effectively machine a taper angle which is partly continuous and in other parts constant by entering in mixture command data for executing taper machining at a specified taper angle and command data for executing taper machining in a specified wire electrode passage on the upper and lower surfaces of a work. CONSTITUTION:When taper machining is performed in a wire discharging machine, command passages of the current block bi and next block bi+1, taper angles alphai, alphai+1 and thickness I of a work are used to obtain the wire electrode location on the lower surface of the work at the end of each block. Therefore, when alphabets U, V are not included in the passage data, NC data of the current block and the next block are used to execute the processing so as to obtain the location (X1, Y1) of the block end on the lower surface of the work, and then location deviation vector u, v at the block and is calculated. Thus, taper machining can be performed easily with high precision.

Abstract: PURPOSE:To sufficiently reinforce a pin and narrow a space necessary for molding of a terminal hole by providing, between the terminal hole and the side surface of a base, a slit for passing the reinforcing rib of the pin for molding the terminal hole along the terminal hole. CONSTITUTION:Between a terminal hole 3 to which a terminal is press-fitted and the side surface of a base 2, a slit 9 for passing the reinforcing rib 8 of a pin 6 for molding the terminal hole 3 is provided along the terminal hole 3. Hence, as the reinforcing rib 8 provided on the pin 6 is entered into a metal mold 4, the rib 8 can be increased in protruding quantity and formed into an optional form, and a space S for forming the terminal hole 3 is never extended even if the protruding quantity of the rib 8 is increased. The formed terminal hole 3 has the slit 9 formed by the rib 8. Thus, as this slit 9 is expanded at the time of terminal press-fitting, there is no fear of cracking of the base 2 and impossibility of press-fitting.
